Chalk-browed Mockingbird / Calandria (Mimus saturninus)

The Chalk-browed Mockingbird is a bird found in Uruguay, most of Brazil, and parts of Bolivia, Paraguay, Argentina, and Suriname. It’s a bird of open wooded areas, including urban and suburban gardens. It feeds on fruits, insects caught on the ground and small vertebrates. Sometimes it preys on other bird’s eggs. It has a large range (around 7,200,000 km²), and although its population has not been thoroughly surveyed, it is believed to be large as it is reported as “common” in parts of its range. The nest is built about 1,5m from the ground on a small tree or scrub. The external part is made of thick branches and the interior of thin roots and grass. It may have up to four broods a year, each one with up to five eggs. Other members of the family may help raising the hatchlings. Chalk-browed Mockingbirds are very aggressive to other species of birds that come close to the nest or feeding sites. In Uruguay and Rio Grande do Sul they have an elaborate song, but in other places the song is simpler. Many mock other bird’s songs such as the kestrel (Falco sparverius). Some populations migrate during the cold season.
